Telewave model tpcd-4554 uhf duplexer
The Telewave Model TPCD-4554 allow simultaneous operation of a transmitter and receiver
into a common antenna. This bandpass duplexers has low insertion loss, and is ideal in
frequency congested areas where protection is needed from surrounding transmitters,
and where maximum transmitter sideband filtering is necessary.
Because of the super i o r construction, these Telewave 5 cavity duplexers achieve greater rejection of
transmitter spurious and noise radiation, providing excellent receiver protection. The TPCD-4554 has
two, - wave bandpass cavities in the transmitter and receiver sections.
These duplexers are designed for transmitters and receivers with frequency spacing of 5 MHz or more.
Selectivity and insertion loss may be adjusted by rotating the calibrated connector loops.
Telewave duplexers have -inch aluminum top plates which are fully welded to the aluminum outer conductor.
Silver-plated tuners, beryllium copper finger stock contactors and threaded Invar rods assure maximum temperature
stability, higher Q , and many years of trouble free operation. If frequency changes are required,
the positive locking mechanism allows for easy field tuning by rotating the threaded Invar rod.
